Google seems to have problems hanging on to top design talent; Doug Bowman's post on leaving Google, and on the culture at the company, was rather revealing for me on that point.
I'm not sure about Google's ability to retain talent... but I'm hopeful that Matias can bring Android some UI/UX love.

Given that, is it really all that unreasonable to point out that Google's UI problems probably are not going to be solved by one person, no matter how much the general community likes him (after all, Bowman's pretty well-loved in the design community, and look what happened to him)?
